14 WYNNE : GEOLOGY OP TPIE SALT EANGE IN THE PUNJAB. 



The reference to the Korana hills^ is, so far as I am aware, the only 

 information extant about their geological structure, except the mention 

 made of them by Mr. Theobald in a paper to be noticed presently. 

 Dr. Fleming could not recognise among their dark-coloured and quartz- 

 veined beds of coarse, brown, ferruginous sandstone, greenish quart- 

 zite and silicious clay slate, any representatives of the Salt Range 

 series, but considered them rather as lower Silurian or Cambrian, and 

 subordinate to the salt formation of the range. No fossils could be 

 detected, but filling small cracks in the sandstone small specimens of 

 pyrolusite or peroxide of manganese were found, and numerous white 

 quartz veins contained masses of rich hsematitic iron ore.f The beds dip 

 to the north-west at angles of 40° to 45°. 



These hills are situated in the Jetch Doab near the River Chenab 

 (or " Ascesines," Elphinstone^s Caubul, page 24) and 24 miles south- 

 eastward of Shahpur. They rise by Dr. Fleming's measurement about 

 957 feet above the plains of the "Bar." 



On the whole, this report is highly interesting and abounds with 

 information. 



A paper by the late distinguished geologist, Sir Roderick I.Murchison, 



with abstracts of letters from Dr. Fleming and his 

 Dr. Fleming and Sir , i z-v 



Roderick I. Murchison, own remarks thereon, appeared in the Quarterly 



Journal of the Geological Society, London, for 



August 1853,J accompanied by a sketch map. 



Dr. Fleming's letters herein alluded to are dated in 1851-52, and 

 express opinions which he altered during his correspondence with Sir 

 Roderick, from whom he learned that salt occurred in all formations
